HOW COPPER WORKS
Research indicates that copper has several modes of action against bacteria. One such mode of action is ion exchange, which researchers believe works like this1:
|
| 1. |
|
Copper surfaces contain copper ions that are recognized by bacteria as an essential nutrient.
|
|
|
|
|
|
|
|
|
|
| 2. |
|
The copper ions enter the bacteria providing a lethal dose that interferes with normal cell function and membrane integrity.
|
|
|
|
|
|
|
|
|
|
| 3. |
|
Cell respiration/metabolism is impeded and DNA damage may occur. The bacteria can no longer consume food or reproduce, and dies.

* Laboratory testing shows that, when cleaned regularly, CuVerro® surfaces kill greater than 99.9% of the following bacteria within 2 hours of exposure: Methicillin-Resistant Staphylococcus aureus, Staphylococcus aureus, Enterobacter aerogenes, Pseudomonas aeruginosa, E. coli O157:H7, and Vancomycin-Resistant Enterococcus faecalis (VRE).
The use of CuVerro™ bactericidal copper products is a supplement to and not a substitute for standard infection control practices; users must continue to follow all current infection control practices, including those practices related to cleaning and disinfection of environmental surfaces. This surface has been shown to reduce microbial contamination, but it does not necessarily prevent cross contamination.
